2013 Porsche Panamera will be powered by twin-turbo V6

Our spy photographers have already caught the facelift version of the Porsche Panamera testing a few times, but until we believed that the luxury sedan will only be modified on the exterior. However, the British magazine Car reports that important changes will also be made under the hood.

It seems that Porsche decided to drop the V8 engine found in the Panamera 4s in favor of a new, high-performance 3.0-litre V6. This new engine will come with twin-turbo capacity and will deliver an impressive 420 HP - a 20 HP increase over the current model.

The new Panamera will also get Audi’s new V8 TDI diesel engine. This decision should not be such a surprise considering the Panamera is quite a hit on the European market.

The new Panamera facelift will arrive in April 2013 and prepares the path for the second generation Panamera that will arrive in 2015 at the Frankfurt Motor Show.
